Hi, Karthik:
Your answers to Alb helped me too.
I have some additional questions:
What will happen if I do the following? (Assuming that TmpImage is also
a smart pointer)
>> ...
>>>> itkFilter1->SetInput( InputImage );
>> itkFilter1->Update();
>> TmpImage = itkFilter1->GetOutput();
>>
InputImage = 0; // added as suggested by Karthik
itkFilter1 = 0; // added by Andrew #1
>> MyClassObject.SetInput( TmpImage );
>> OutputImage = MyClassObject.GetOutput();
>>
TmpImage = 0; // added by Andrew #2
>> ...
>>
Is there any advantage or problem from this inserted line?
itkFilter1 = 0; // added by Andrew #1
I assume that this line will force everything pointed by itkFilter1 to
be released except the object pointed by TmpImage. Is it correct?
And the remaining resources: the object pointed by TmpImage will be
release at inserted line #2:
TmpImage = 0; // added by Andrew #2
And, thus, there will be no problem such as memory leaks.
Thank you very much for your help!
